Input/Output to Screen

Python standard output file is not available when running Python macros from Tools – Macros - Run Macro... menu. Presenting the output of a module requires the Python interactive console. Features such as input(), print(), repr() and str() are available from the Python shell.

LibreOffice msgbox Python module proposes a msgbox() method that is illustrated in Creating Event Listeners and Creating a dialog handler example pages.

O LibreOffice Basic oferece as funções de E/S de ecrã InputBox(), Msgbox() e Print(). As alternativas Python existem a partir tanto do LibreOffice API Abstract Windowing Toolkit, quanto pelas chamadas para o BASIC do Python. Esta última oferece uma sintaxe intencionalmente similar ao BASIC, e utiliza um módulo Python junto com um módulo BASIC. Utiliza-se o API Scripting Framework para executar chamadas de função entre BASIC, BeanShell, JavaScript e Python.

Sintaxe Python:

MsgBox(txt, buttons=0, title=None)

InputBox(txt, title=None, default=None)

Print(txt)

Exemplos:

>>> import screen_io as ui

>>> reply = ui.InputBox('Please enter a phrase', title='Dear user', defaultValue="here..")

>>> rc = ui.MsgBox(reply, title="Confirmation of phrase")

>>> age = ui.InputBox('How old are you?', title="Hi")

>>> ui.Print(age)

MsgBox and InputBox methods from the Basic service included in the ScriptForge libraries call directly their native Basic counterparts.

                Optional title As String ) As Integer

The Alternative Python Script Organizer (APSO) extension offers a msgbox() function out of its apso_utils module.
